Abstract
The utility model discloses an aeration device which comprises a shell, helical blades, a draft tube and a gas distribution tube, wherein the chamber of the shell is provided with three cylinder channels, while each channel has several sections and each section is provided with helical blades twisted of 180 degrees, the rotation direction of the helical blades in one section are same, the rotation directions of the helical blades in nearby two sections are reverse, the cylinder channels are alternatively arranged, the aeration device is supported by a carrier, the bottom of the shell is provided with a cylinder draft tube, the gas distribution tube is arranged at the bottom of the shell, whose one end is provided with a discharge cap. The dual-helical aeration device is mounted in water, air is fed into the aeration device at the bottom, and bubbles are cut repeatedly via rotation, radical mixing and reverse rotation to be beneficial for oxygen transfer. And since the density of mixing solution is reduced, the utility model can form large increase flow speed and lifting function to accelerate the water around the aeration device to flow toward the tank bottom, thereby accelerating the water flow circulation to improve oxygen charge ability. The bottom of the aeration device is provided with a draft tube to strengthen the reflux lifting function of mud and improve the oxygen charge efficiency of the aeration device.
Description
Technical field
The utility model relates to a kind of waste disposal plant, is specifically related to a kind of aerating apparatus.
Background technology
In the prior art, aerator is widely used in trade effluent and municipal sewage treatment fields such as petrochemical complex, printing and dyeing, synthon, food, agricultural chemicals, makes the abundant oxygenation of water.The duplex aerator is common aerator, is made up of housing, left-handed plate, dextrorotation plate and gas-distribution pipe etc., and this aerating apparatus exists oxygenic aeration poor, and oxygen-transfer efficiency is not high, susceptible to plugging shortcoming.
Summary of the invention
The purpose of this utility model is to provide a kind of aerating apparatus that improves oxygenation capacity and efficient.
The technical solution of the utility model is: aerating apparatus comprises housing, screw-blade, guide shell and gas-distribution pipe, the housing inner chamber is provided with three cylindrical channels, each cylindrical channel has some joints, be equipped with the screw-blade of 180 ° of distortions in every joint passage, the sense of rotation of screw-blade is identical in same joint passage, screw-blade sense of rotation in adjacent two joints is opposite, the setting that interlaces of every pitch circle cylindrical passageway; Aerating apparatus is by stent support, and housing bottom is provided with cylindrical guide shell, and gas-distribution pipe is arranged on housing bottom, and an end is provided with the emptying cap.
The utility model aerating apparatus is installed in the water, this device is provided with three groups of cylindrical channels, every group of passage is equipped with a screw-blade, air enters from aerating apparatus bottom, bubble through the rotation of three groups of screw-blades, radially mix, reverse rotation, thereby repeatedly be cut, bubble constantly diminishes, the continuous blending of gas-liquid, contact area constantly increases, and helps the transfer of oxygen.Diminish because of mixed solution density simultaneously, can form bigger upflow velocity and castering action, make aerating apparatus water on every side moving, impel the current systemic circulation, improve oxygenation capacity to the pond underflow.In the aerating apparatus bottom guide shell is set,, improves the oxygen-transfer efficiency of aerating apparatus to strengthen mud backflow castering action; Gas-distribution pipe is provided with the emptying cap so that discharge settling, prevents line clogging.
Description of drawings
Fig. 1 is the stereographic map of the utility model aerating apparatus.
Embodiment
As shown in the figure, aerating apparatus comprise housing 1, screw-blade 3,3 ', guide shell 4 and gas-distribution pipe 5, the housing inner chamber is provided with three cylindrical channels, each cylindrical channel at least three joint, the sense of rotation of 3, three screw-blades 3 of right-hand screw blade that is equipped with 180 ° of distortions in three cylindrical channels 2 is identical.Adjacent two pitch block passages 2 ' in be provided with the left-hand screw blade, opposite with screw-blade 3 sense of rotation in the adjacent segments.The setting that interlaces of every pitch circle cylindrical passageway; Aerating apparatus is supported by support 6, and housing bottom is provided with cylindrical guide shell 4, and gas-distribution pipe 5 is arranged on the housing bottom below, and gas-distribution pipe one end is provided with emptying cap 7.
